Clinical Results of Carpal Tunnel Release Using Ultrasound Guidance in Over 100 Patients at Two to Six Years

PurposeThe purpose of this study was to determine the clinical results of carpal tunnel release using ultrasound guidance (CTR-US) at a minimum of 2 years post-procedure. MethodsThe study consisted of 102 patients (162 hands) treated with CTR-US by the same physician between June 2017 and October 2020 for whom minimum 2-year follow-up data were available. Questionnaires were sent to gather long-term information, with additional phone calls for clarification if needed. Outcomes included Boston Carpal Tunnel Questionnaire symptom severity (BCTQ-SSS) and functional status (BCTQ-FSS) scores, Quick Disabilities of the Arm, Shoulder, and Hand (QDASH) scores, global satisfaction scores, and subsequent surgeries. ResultsThe 102 patients included 68 females and 34 males with a mean age of 56.9 years at the time of surgery. Fifty-five (53.9%) patients had simultaneous bilateral procedures, 42 (41.2%) had unilateral procedures, and 5 (4.9%) had staged bilateral procedures. Significant improvements in BCTQ-SSS, BCTQ-FSS, and QDASH scores persisted at a mean final follow-up of 46 months (range 2-6 years). At final follow-up, 91.2% of patients reported satisfaction with the procedure. No outcomes were significantly different between those treated with simultaneous bilateral versus unilateral procedures. No revision surgeries were reported. ConclusionsCTR-US is a safe and effective procedure that results in significant improvements that persist up to 6 years post-procedure. Long-term results of simultaneous bilateral and unilateral procedures are similar. Level of EvidenceIV therapeutic

Final 1-Year Results of the TUTOR Randomized Trial Comparing Carpal Tunnel Release with Ultrasound Guidance to Mini-open Technique.

Studies comparing carpal tunnel release with ultrasound guidance (CTR-US) to mini-open CTR (mOCTR) are limited. This randomized trial compared the efficacy and safety of these techniques. In this multicenter randomized trial, patients were randomized (2:1) to unilateral CTR-US or mOCTR. Outcomes included Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and Functional Status Scale (BCTQ-FSS), numeric pain scale (0-10), EuroQoL-5 Dimension 5-Level (EQ-5D-5L), scar outcomes, and complications over 1 year. Patients received CTR-US (n = 94) via wrist incision (mean 6 mm) or mOCTR (n = 28) via palmar incision (mean 22 mm). Comparing CTR-US with mOCTR, the mean changes in BCTQ-SSS (-1.8 versus -1.8; P = 0.96), BCTQ-FSS (-1.0 versus -1.0; P = 0.75), numeric pain scale (-3.9 versus -3.8; P = 0.74), and EQ-5D-5L (0.13 versus 0.12; P = 0.79) over 1 year were comparable between groups. Freedom from scar sensitivity or pain favored CTR-US (95% versus 74%; P = 0.005). Complications occurred in 2.1% versus 3.6% of patients (P = 0.55), all within 3 weeks postprocedure. There was one revision surgery in the CTR-US group, and no revisions for persistent or recurrent symptoms in either group. CTR-US and mOCTR demonstrated similar improvement in carpal tunnel syndrome symptoms and quality of life with comparable low complication rates over 1 year of follow-up. CTR-US was performed with a smaller incision and associated with less scar discomfort.

Hereditary neuropathy associated with liability to pressure palsies: a 24-year experience with carpal and cubital tunnel surgery.

The aim of this single-centre retrospective study was to evaluate the outcomes of carpal tunnel release surgery in patients with hereditary neuropathy with pressure palsies (HNPP). The secondary aims were to identify prognostic factors for the outcome of carpal tunnel release and to assess the outcome of cubital tunnel release. Our primary hypothesis was postoperative improvement. In total, 18 patients (26 carpal tunnel releases) with at least one symptomatic carpal tunnel syndrome were included. At a median follow-up of 8.5 years, more than 73% of the patients were satisfied with the results. The visual analogue scale (0 to 10) for discomfort decreased by 2.2 points (p < 0.001). The Boston Carpal Tunnel Questionnaire symptom severity scale decreased by 1.3 points (p < 0.001). The decrease in the Functional Status Scale was not significant. No significant prognostic factor for outcome was identified. A total of 12 patients also underwent cubital tunnel release, and three patients underwent just this procedure (23 procedures). Despite the lack of preoperative data, cubital tunnel release provided encouraging results. Level of evidence: III.

Best-Evidence Systematic Review and Meta-Analysis of Endoscopic Carpal Tunnel Release Outcomes

The aim of this systematic review and meta-analysis was to evaluate the safety and effectiveness of endoscopic carpal tunnel release (ECTR) using best-evidence synthesis methods. A systematic search of multiple databases was conducted for prospective contemporary studies published between January 2013 and January 2023 with at least 50 ECTR cases. Outcomes included the Quick Disabilities of the Arm, Shoulder, and Hand Questionnaire (Q-DASH) measured on a 0-100 scale, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and Functional Status Scale (BCTQ-FSS) on a 1-5 scale, pain visual analog scale on a 0-10 scale, conversion to open carpal tunnel release (CTR), complications, and reoperations. Outcomes were analyzed using a random-effects meta-analysis model. Metaregression was used to determine the association of patient- and study-level factors with ECTR outcomes. A total of 17 studies with 1,632 patients treated with ECTR were included. Median follow-up durations ranged from 4 to 7 months depending on the outcome. Statistically significant and clinically important improvements were noted after ECTR for Q-DASH, BCTQ-SSS, BCTQ-FSS, and pain visual analog scale scores, with mean differences from baseline of-28.8,-1.8,-1.5, and-5.1, respectively (P < .001 for all). In metaregression, the strongest predictor of improvement in Q-DASH, BCTQ-SSS, and BCTQ-FSS was a greater preoperative score for that variable (all P ≤ .005), indicating that patients with worse symptoms improved the most. The risks of conversion to open CTR, complications, and revision CTR were 0.7%, 0.7%, and 0.5%, respectively. In a best-evidence synthesis of contemporary studies, ECTR resulted in significant improvements in function and pain, with a low risk of conversion to open surgery, complications, and reoperations over short-term follow-up. Patients treated with ECTR can expect generally favorable clinical outcomes over the short term. However, long-term outcomes after ECTR are not well characterized.

Carpal Tunnel Release With Ultrasound Guidance: Intermediate-Term Clinical Outcomes and Magnetic Resonance Imaging Findings

The purpose of this study was to report intermediate-term outcomes following carpal tunnel release using ultrasound guidance and wide-awake local anesthesia no tourniquet, including a subset of patients with preoperative and postoperative magnetic resonance imaging (MRI). In this observational study, patients with carpal tunnel syndrome were treated with carpal tunnel release using ultrasound guidance and wide-awake local anesthesia no tourniquet in a procedure room at a single center. Main outcomes were complications; return to activity and work at 2 weeks; Quick Disabilities of the Arm, Shoulder, and Hand and Boston Carpal Tunnel Questionnaire scores through 6 months; and postoperative morphological changes of the transverse carpal ligament, median nerve, and carpal tunnel evaluated using MRI. No complications were reported among 65 patients (68% women, 96 wrists). By 2 weeks, 97% of patients returned to normal activity and 100% returned to work. Statistically significant improvements in Boston Carpal Tunnel Questionnaire symptom severity scale, Boston Carpal Tunnel Questionnaire functional status scale, and Quick Disabilities of the Arm, Shoulder, and Hand scores occurred by the 2-week follow-up interval and persisted at 6 months (all P < .001). Pre- and postoperative MRI scans were available for 13 patients (17 wrists) at the 3-month mean follow-up. Complete transverse carpal ligament transection was documented in all wrists. Key MRI findings included a 22% increase in carpal tunnel cross-sectional area at the hamate (P < .001), a 52% increase in median nerve cross-sectional area at the hamate (P < .001), an 18% reduction in median nerve signal intensity (P= .002), a 38% reduction in the flattening ratio of the median nerve at the hamate (P < .001), a 33% reduction in the flattening ratio of the median nerve at the pisiform (P < .001), a 20% reduction in the flattening ratio of the carpal tunnel at the hamate (P < .001), and a palmar shift of the median nerve relative to the hamate in all cases. Carpal tunnel release using ultrasound guidance using wide-awake local anesthesia no tourniquet in a procedure room setting was safe, effective, and resulted in morphological changes that were consistent with carpal tunnel decompression as demonstrated by MRI. Therapeutic IV.

Multicenter randomized trial of carpal tunnel release with ultrasound guidance versus mini-open technique

ABSTRACT Background Comparative studies of carpal tunnel release with ultrasound guidance (CTR-US) vs. mini-open CTR (mOCTR) are limited, prompting development of this randomized trial to compare efficacy and safety of these techniques. Research design and methods Patients were randomized (2:1) to CTR-US or mOCTR, treated by experienced hand surgeons (median previous cases: 12 CTR-US; 1000 mOCTR), and followed for 3 months. Results Among 149 randomized patients, 122 received CTR-US (n = 94) or mOCTR (n = 28). Mean incision length was 6 ± 2 mm in the wrist (CTR-US) vs. 22 ± 7 mm in the palm (mOCTR) (p < 0.001). Median time to return to daily activities (2 vs. 2 days; p = 0.81) and work (3 vs. 4 days; p = 0.61) were similar. Both groups reported statistically significant and clinically important improvements in Boston Carpal Tunnel Questionnaire Symptom Severity and Functional Status Scales, Numeric Pain Scale, and EuroQoL-5 Dimension 5-Level, with no statistical differences between groups. Freedom from wound sensitivity and pain favored CTR-US (61.1% vs. 17.9%; p < 0.001). Adverse event rates were low in each group (2.1% vs. 3.6%; p = 0.55). Conclusions The efficacy and safety of CTR-US were comparable to mOCTR despite less previous surgical experience with CTR-US. The choice of CTR technique should be determined by shared decision-making between patient and physician. Clinical trial registration www.clinicaltrials.gov identifier is NCT05405218.

Protocol of a Multicenter Prospective Trial of Office-Based Carpal Tunnel Release With Ultrasound Guidance (ROBUST).

Background Carpal tunnel release (CTR) is a common surgical procedure for patients with severe or refractory carpal tunnel syndrome (CTS) symptoms. Historically, CTR procedures have been performed in a hospital or an ambulatory surgery center (ASC). However, due to advancements in techniques, greater patient demand, and concerns about growing healthcare costs, there is a distinct trend toward performing CTR procedures in an office-based setting. Several small studies with limited follow-up duration have demonstrated the feasibility of CTR with ultrasound guidance (CTR-US) when performed in an office-based setting. The objective of this study is to evaluate the safety and effectiveness of office-based CTR-US in a large cohort of patients (n=140) with symptomatic CTS followed for two years post-treatment. Design and methods ROBUST is a prospective multicenter observational study in which 140 subjects at up to 12 sites in the United States will be treated with CTR-US in an office-based setting. The primary endpoint of the study is the change in the Boston Carpal Tunnel Questionnaire Symptom Severity Scale score. Secondary endpoints include time to return to normal daily activities, time to return to work among employed subjects, change in the Boston Carpal Tunnel Questionnaire Functional Status Scale score, change in the Michigan Hand Questionnaire overall and domain scores, change in the Numeric Pain Scale score, change in the EuroQoL-5 Dimension 5-Level score, global satisfaction scores, and the incidence of deviceor procedure-related adverse events. The primary analysis of study endpoints will occur three months post-treatment. Patient follow-up in this study will continue for two years. Conclusions A central institutional review board approved the study protocol, and a data safety monitoring board will provide study oversight. The authors plan to report study results at medical conferences and in peer-reviewed medical journals. The outcomes of ROBUST will provide physicians, patients, and payors with important safety and effectiveness data regarding the clinical utility of CTR-US when performed in an office setting.

Symptom Outcome of Walant Technique for Carpal Tunnel Release – A Prospective Study in the Tertiary Care Hospital, Nowshera

OBJECTIVES The study aims to determine the outcome of the WALANT technique for Carpal Tunnel Release CTR.METHODOLOGY A descriptive study was done in the Neurosurgery department at Qazi Hussain Ahmad Medical Complex, Nowshera, from 15th September 2020 to 15th March 2021. A total of 29 consecutive patients of carpal tunnel syndrome (CTS) were undergoing carpal tunnel release (CTR) under wide awake local anaesthesia no tourniquet (WALANT) technique, using a mixture of lidocaine and epinephrine for local anaesthesia, and the outcome was assessed for patient satisfaction by Boston Carpal Tunnel Questionnaire (BCTQ) (symptom severity scales (SSS)) at pre-operatively and six weeks postoperatively.RESULTSWide awake CTR was done in 29 patients; 86.2% were female and 13.8% male. The mean age was 47.3 years. The average time of return to daily activity was three weeks. No complications were noted, like wound infection and dehiscence. BCTQ symptom (BCTQ-S) score significantly improved at six weeks postoperatively. 86% significantly reduced the symptom severity score (SSS). Mean SSS improved from preoperative 3.2 points to 1.7 points postoperatively. There was a significant decrease in distal latencies (p &lt;0.01). CONCLUSIONWide awake surgery is an excellent technique with favourable outcomes and good satisfaction rates for CTR. The study shows that clinical symptoms resolve rapidly after CTR. Without the need for monitored anaesthesia, the cost could decrease dramatically.

A preliminary study of radioulnar wrist compression in improving patient-reported outcomes of carpal tunnel syndrome

Previous studies have shown radioulnar wrist compression augments carpal arch space. This study investigated the effects of radioulnar wrist compression on patient-reported outcomes associated with carpal tunnel syndrome. Subjects underwent thrice-daily (15 min each time 45 min daily) wrist compression over 4 weeks with an additional four weeks of follow-up without treatment. Primary outcomes included Boston Carpal Tunnel Questionnaire symptom and functional severity scales (SSS and FSS) and symptoms of numbness/tingling based on Visual Analog Scales. Our results showed that radioulnar wrist compression improved SSS by 0.55 points after 2 weeks (p < 0.001) and 0.51 points at 4 weeks (p < 0.006) compared to the baseline scale. At the four-week follow-up, SSS remined improved at 0.47 points (p < 0.05). Symptoms of numbness/tingling improved at two and 4 weeks, as well as the follow-up (p < 0.05). Hand motor impairment such as weakness had a lower frequency across carpal tunnel syndrome sufferers and does not significantly improve (p > 0.05). Radioulnar wrist compression might be an effective alternative treatment in improving sensory related symptoms in patients with mild to moderate carpal tunnel syndrome.

Mega Nerves: Factors Associated with Large Median Nerves on Ultrasound of the Carpal Tunnel.

Background:Although increased cross-sectional area of the median nerve on ultrasound has been associated with carpal tunnel syndrome, there has been little research examining outlier cases with exceedingly large nerves. The purpose of this study was to identify factors associated with these “mega” nerves, and to determine whether these nerves carry with them increased severity of disease.Methods:Patients who presented to clinic with upper extremity paresthesias over a 4-year period were included in this study. Two groups were created: mega nerves (cross-sectional area >2 SD above average), and nonmega nerves. Statistical analysis was performed to compare demographics, symptom scores, and nerve conduction studies (NCS). Significant variables were then compared between patients with mega nerves and those with ultrasound positive nerves (≥10 mm2), which did not reach mega size (normal nerves were excluded).Results:The cohort included 425 median nerves with 25 mega nerves. The groups differed significantly in diabetes status, body mass index (BMI), Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity Scale scores, and NCS results. When compared only with ultrasound positive but nonmega nerves, mega nerves were still associated with diabetes, higher BMI, and worse NCS results.Conclusions:Diabetes, BMI, NCS results, and BCTQ Symptom Severity Scale scores are associated with mega nerves. However, BCTQ scores do not differ between mega nerves and other ultrasound positive nerves. In patients with obesity or diabetes, outlier ultrasound measurements may not correlate with worsened clinical symptoms, even in the setting of more significantly altered NCS results.

Trial of ultrasound guided carpal tunnel release versus traditional open release (TUTOR).

Background:Carpal tunnel release (CTR) is a surgical treatment option for patients with carpal tunnel syndrome (CTS) symptoms that are unresponsive to conservative treatment. Most patients experience symptomatic relief after CTR regardless of the surgical technique. However, direct comparisons of the safety and effectiveness between CTR surgical techniques are limited. The purpose of this randomized controlled trial is to compare the safety and effectiveness of CTR with ultrasound guidance (CTR-US) versus mini-open CTR (mOCTR) in subjects with symptomatic CTS.Design and methods:TUTOR (Trial of Ultrasound guided CTR versus Traditional Open Release) is a randomized controlled trial in which 120 subjects at up to 12 sites in the United States will be randomized (2:1) to receive CTR-US or mOCTR. The primary endpoint of the study is the percentage of patients who return to normal daily activities within 3 days of the procedure. Secondary endpoints of the study are median time to return to normal daily activities, percentage of patients who return to work within 3 days of the procedure, median time to return to work, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) change score at 3 months, BCTQ Functional Status Scale (BCTQ-FSS) change score at 3 months, Numeric Pain Scale change score at 3 months, EuroQoL-5 Dimension 5-Level (EQ-5D-5L) change score at 3 months, and the incidence of device- or procedure-related adverse events at 3 months. Patient follow-up in this trial will continue for 1 year.Ethics and dissemination:This study was approved by a central institutional review board and ongoing trial oversight will be provided by a data safety monitoring board (DSMB). The authors intend to report the results of this trial at medical conferences and peer-reviewed journals. The outcomes of TUTOR will have important clinical and economic implications for all stakeholders involved in treating patients with CTS.Study registration:ClinicalTrials.gov (https://clinicaltrials.gov): NCT05405218.Level of evidence:1

Comparison of Distal and Proximal Local Steroid Injection for Carpal Tunnel Syndrome: a Systematic Review and Meta-analysis of Randomized Controlled Trials.

Local steroid injection (LSI) in the carpal tunnel is a mainstay of conservative treatment in patients with carpal tunnel syndrome (CTS). Currently, clinicians generally perform a conventional proximal approach (PA) or novel distal approach (DA) for LSI. Recent systematic reviews comparing the two injection methods are lacking. This systematic review and meta-analysis aimed to assess whether LSI using the DA was superior to PA in treating patients with CTS. Databases including Pubmed, Embase, and the Cochrane library were searched up to 30 May 2022 to identify relevant randomized controlled trials (RCTs) comparing the DA with the PA steroid injection in patients with CTS. The outcomes mainly included Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQs) and Functional Status Scale (BCTQf), visual analog scores (VAS), electrophysiological outcomes, pain of injection, duration of injection, or adverse events. Five RCTs involving 339 patients were identified. Pooled analysis showed that the DA group took less time [mean difference (MD) -19.91; 95% CI -34.48 to -5.35; P = 0.007] and acquired better sensory nerve action potential amplitude [standardized mean difference (SMD) -0.37; 95% CI -0.62 to -0.11; P = 0.005]. The two groups were not significantly different in terms of BCTQs and BCTQf, VAS, other electrophysiological outcomes, pain of injection, or adverse events (P > 0.05). Although providing similar improvement in pain relief or function improvement, the distal approach is superior to the proximal approach in terms of timing, without increasing other side effects. Further high-quality randomized studies are required to confirm these results.

Changes in Cross-sectional Area of the Median Nerve and Boston Carpal Tunnel Questionnaire Scores After Carpal Tunnel Release.

We hypothesized that postoperative Boston Carpal Tunnel Questionnaire (BCTQ) scores and ultrasound (US) measurements of the median nerve cross-sectional area (CSA) at the distal wrist crease are significantly decreased at 2-week, 6-week, and ≥ 6 months follow-up appointments, compared with baseline values. This study was a retrospective chart review of patients who presented to a single hand clinic with evidence of carpal tunnel syndrome over a 6-year period (2014-2020). Patients received baseline US measurements of the median nerve CSA as well as completion of the BCTQ, and for the patients who underwent carpal tunnel release (CTR), postoperative US measurements and questionnaire scores were obtained at 2 weeks, 6 weeks, or ≥ 6 months postoperatively. This study included 224 separate wrists. Median Nerve CSA measurements were 13.2 ± 4.5 mm2 at baseline, 11.9 ± 3.6 mm2 at 2 weeks postoperatively, 11.6 ± 4.5 mm2 at 6 weeks postoperatively, and 11.7 ± 4.3 mm2 at 6 months or more (P = .002). The BCTQ Symptom Severity Scale scores were 3.14 ± 0.76 at baseline, 1.76 ± 0.63 at 2 weeks, 1.68 ± 0.70 at 6 weeks, and 1.41 ± 0.64 at 6 months or longer (P < .001). The BCTQ Functional Status Scale scores were 2.56 ± 0.89 at baseline, 2.03 ± .1.0 at 2 weeks, 1.65 ± 0.77 at 6 weeks, and 1.36 ± 0.61 at 6 months or longer (P < .001). These findings demonstrated a sustained decrease in median nerve CSA and patient-reported outcomes following CTR at 2 weeks, 6 weeks, and between 6 and 12 months.

Manual Therapy and Related Interventions for Carpal Tunnel Syndrome: A Systematic Review and Meta-Analysis.

Objective: Systematic review and meta-analysis to assess the efficacy of Manual therapy and related interventions in the treatment of carpal tunnel syndrome (CTS) based on Boston carpal tunnel questionnaire. Design: Systematic review and meta-analysis. Subjects: Carpal tunnel syndrome. Interventions: Manual therapy and related interventions versus other therapies or manual therapy and related interventions plus other therapies versus other therapies. Outcomes measures: Boston carpal tunnel questionnaire. Results: A total of 6 studies were included, including 211 cases in the manual therapy group and 211 cases in the control group. The quality of the included articles was high, and the results of meta-analysis showed that manual therapy and related interventions were superior in terms of improving the Boston carpal tunnel questionnaire Symptom Severity score in patients with CTS (standardised mean difference [SMD] -1.13, 95% CI -1.40 to -0.87), were superior to control groups in terms of improving the Boston carpal tunnel questionnaire functional capacity scale in patients with CTS (SMD -1.01,95% CI -1.24 to -0.77). Conclusion: The results of this meta-analysis suggested that manual therapy and related interventions were better than control groups in treating CTS. Manual therapy and related interventions could relieve the symptoms of patients with CTS and promote the recovery of hand function. Manual therapy and related interventions should be considered clinically effective methods for treating CTS. Registration: The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO; No. CRD 42020201389). Contribution of the Article: Manual therapy and related interventions could relieve the symptoms of patients with CTS and promote the recovery of hand function. Manual therapy and related interventions should be considered clinically effective methods for treating CTS.

Multicenter pragmatic study of carpal tunnel release with ultrasound guidance

ABSTRACT Objectives To report outcomes of patients who underwent carpal tunnel release with ultrasound guidance (CTR-US) in routine clinical practice. Methods This was a multicenter post-market registry of patients treated with CTR-US. Main outcomes included the Quick Disabilities of Arm, Shoulder, and Hand Questionnaire (QDASH), Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and Functional Status Scale (BCTQ-FSS), return to normal activities, return to work, and complications. Results Of 535 patients who provided follow-up data, 373 (70%) were followed for 6 months post-treatment. Among these 373 patients (427 hands, mean age 55 years, 71% female), QDASH scores decreased by 30.8 points, BCTQ-SSS scores decreased by 1.6 points, and BCTQ-FSS scores decreased by 1.0 points at 6 months (all p < 0.001). The median time to return to normal activities was 3 days and time to return to work was 5 days. Subgroup analysis revealed consistent outcomes regardless of age group, sex, body mass index, diabetes, tobacco use, worker compensation status, or procedure type (unilateral/bilateral simultaneous). No major neurovascular complications were reported. Conclusion Patients treated with CTR-US reported clinically meaningful improvements in symptoms and function, rapid return to normal activities, and minimal work absenteeism, with an excellent safety profile.

Boston Carpal Tunnel Questionnaire Scores Alone Do Not Predict Surgical Intervention for Patients With Carpal Tunnel Syndrome.

With the expanded indications for telemedicine, there is increased utility for screening methods to determine which patients are likely to progress to surgical intervention, requiring in-person visits. Patient-rated tools such as the Boston Carpal Tunnel Questionnaire (BCTQ) may be one such tool for screening patients with carpal tunnel syndrome (CTS). The aim of the study was to evaluate whether BCTQ scores were predictive of offering conservative treatment or surgical intervention for CTS. Patients diagnosed with CTS from January 2017 to February 2020 completed BCTQ questionnaires prior to in-person office visits. Demographics, comorbidities, and highest level of intervention recommended were recorded for each patient as conservative, injection, or surgery. Pearson χ2 and independent-samples t tests were conducted to determine whether BCTQ symptom severity and functional scores were associated with intervention type. A total of 200 patients with CTS were included. Of these, 103 were recommended conservative or injection treatment and 97 were recommended surgery. There were no differences in comorbidities between groups, including other upper extremity pathology (P = .57), previous upper extremity surgery (P = .32), hypertension (P = .17), hypothyroidism (P = .15), rheumatoid arthritis (P = .34), and diabetes (P = .30). Between these groups, there were no differences in BCTQ symptom severity score (symptom severity scale [SSS]; P = .16) or BCTQ functional severity score (functional severity scale [FSS]; P = .96). There is no correlation between comorbidities and BCTQ SSS or FSS score, and offering surgery for CTS. In an era of minimizing non-essential health care visits, the BCTQ is insufficient in screening patients as potential surgical candidates.

Predicting Clinically Relevant Patient-Reported Symptom Improvement After Carpal Tunnel Release: A Machine Learning Approach.

Symptom improvement is an important goal when considering surgery for carpal tunnel syndrome. There is currently no prediction model available to predict symptom improvement for patients considering a carpal tunnel release (CTR). To predict using a model the probability of clinically relevant symptom improvement at 6 mo after CTR. We split a cohort of 2119 patients who underwent a mini-open CTR and completed the Boston Carpal Tunnel Questionnaire preoperatively and 6 mo postoperatively into training (75%) and validation (25%) data sets. Patients who improved more than the minimal clinically important difference of 0.8 at the Boston Carpal Tunnel Questionnaire-symptom severity scale were classified as "improved." Logistic regression, random forests, and gradient boosting machines were considered to train prediction models. The best model was selected based on discriminative ability (area under the curve) and calibration in the validation data set. This model was further assessed in a holdout data set (N = 397). A gradient boosting machine with 5 predictors was chosen as optimal trade-off between discriminative ability and the number of predictors. In the holdout data set, this model had an area under the curve of 0.723, good calibration, sensitivity of 0.77, and specificity of 0.55. The positive predictive value was 0.50, and the negative predictive value was 0.81. We developed a prediction model for clinically relevant symptom improvement 6 mo after a CTR, which required 5 patient-reported predictors (18 questions) and has reasonable discriminative ability and good calibration. The model is available online and might help shared decision making when patients are considering a CTR.

A Novel Supraretinacular Endoscopic Carpal Tunnel Release: Surgical Technique, Clinical Efficacy and Safety (A Series of 48 Consecutive Cases)

PurposeEndoscopic carpal tunnel release has been shown to have a shorter recovery period than open surgery. This study was aimed at assessing the efficacy and possible clinical complications of a novel supraretinacular endoscopic carpal tunnel release technique.MethodsA total of 50 cases involving 46 patients were evaluated in this prospective study, in which all surgeries were performed by a single surgeon between 2016 and 2018. The patients were evaluated preoperatively; at 3, 7, and 14 days after surgery; and at 1, 3, and 6 months after surgery. The effectiveness of the surgery was evaluated using pinch and grip strengths, modified table test, visual analog scale pain score, the Disabilities of the Arm, Shoulder and Hand, the Boston Carpal Tunnel Questionnaire symptom severity scale, and the Boston Carpal Tunnel Questionnaire functional status scale. The Friedman test and Wilcoxon signed-rank test were used for a statistical analysis.ResultsAt 6 months after the surgery, all measured parameters showed improvements. The pinch strength score improved from 2.29 kg before the surgery to 2.96 kg 6 months after the surgery (P = .003), the grip strength score improved from 12.10 kg to 13.98 kg (P = .028), the modified table test score increased from 6.55 kg to 8.76 kg (P < .001), the visual analog scale score decreased from 6.31 to 0.52 (P < .001), the Disabilities of the Arm, Shoulder and Hand score reduced from 41.66 to 14.10 (P < .001), and the Boston Carpal Tunnel Questionnaire symptom severity scale and the Boston Carpal Tunnel Questionnaire functional status scale scores reduced from 2.68 to 1.51 (P < .001) and from 2.56 to 1.44 (P < .001), respectively. There were no serious injuries or complications reported in this series.ConclusionsThis new supraretinacular endoscopic carpal tunnel release technique was shown to be efficacious in this series.Type of study/level of evidenceTherapeutic IV.
